Hello All,
I need to limit the Multi select list box to 2. User could select only 2 values.
Refer the link:

Please help me to achieve this. User can select 2 values then the list should be disabled. But at the same time user can de-select the values which is already selected. Then all the options should be available as the length is one.
If the length is equal to 2 then we need to block the selection.

I created a programming example to explain this:

You can disable the listbox with this code:
$("#myListboxId").getControl().prop("disabled", true);
But if you do that, then there is no way to change the selected items. You will have disable individual options in the listbox. Sorry, but I'm already spent an hour preparing the previous example for you so you will have to figure it out on your own.

Oh, I just noticed that you posted this under ProcessMaker 2. Are you using version 2?

Hello Amos,
The following solution is working.
Code: Select all$("#var_Dropdown_Multiselect").setOnchange(function(newVal, oldVal){
if (newVal.length > 3) {
$("#var_Dropdown_Multiselect").setValue(eval(oldVal));
}
});
